CHARLES C. BRIAND, OF REVERE, MASSACHUSETTS, ASSIGNOR TO PETER GRAY &,SONS, A CORPORATION OF MASSACHUSETTS.

LANTERN OR LAMP.

Specification of Letters Patent.

Patented May 20, 1913.

Application filed. October 8, 1908. Serial No. 456,834.

To all whom it may concern Be it known that I, CHARLES C. BRIAND, acitizen of the United States, residing in Revere, county of Suffolk,Commonwealth of Massachusetts, have invented certain new and usefulImprovements in Lanterns or Lamps, of which the following is aspecification, reference being had to the drawings accompanying the sameand forming a partthereof.

My invention relates to lanterns or lamps used particularly forsignaling purposes.

The object of my invention is to provide means in a lantern or lamp sothat the color of the light rays projected from them may be'quicklychanged to display the desired color.

In the drawings accompanying this specification and forming a partthereof-Figure 1 is a side elevation of a lantern or lamp showing themovable lens-holders in dotted lines; and Fig. 2 is a sectional planview taken through line 22, Fig. 1.

In the drawings, 1 represents the body of the lantern or lamp ;and 2 anangular piece secured to the inside of the body 1 and which is designedto act as a hearing or support for the guiding cone 3. The cone 4 ismounted to revolve in the cone 3, fitting fairly close therein. It isprovided with a milled or knurled bezel or ring which secures the lenses6 to the cone 4.

7 is a movable lens-holder which is pivoted to the angular piece 2 bythe pivot 8 so that it will rotate thereon and .is provided with anangular slot 9 having a straight; portion and a curved portion adaptedto re-.

ceive a pin 10 in such manner that saidpin can slide in said slot. Thepin 10 is secured in the flange of the revolving cone 4 so that whensaid cone 4 is revolved the pin. 10 will slide in the straight part ofthe slot 9 and swing the lens-holder 7 upon the pivot 8 to present it tocover the central opening in the cone 4 so that any light within thelantern body 1 will shine through the lens 11 mountsecured in it a lensof another color. It is pivoted to the angular piece 2 by the pivot 13and is provided with the angular slot 14 and a pin 15 slidable in saidangular slot so that when the cone 4 is revolved the pin 15 will slidein the straight part of the slot 14 and rotate the lens-holder 12 uponits pivot 13 either to be presented to the opening in the cone 4 orswung to the position shown in Fig. 1. The lens 6 is preferably of whiteglass so that it will project white light rays. The other lenses may bered and green, or violet and blue, or any desired colors, so that whenthe lens 11 is presented in front of the opening in the cone 4 it willshow onecolor and when the lens 16 in the lens-holder 12 is presented infront of the opening it will show another color.

A stop and locking arrangement is provided by which to position thelens-holders 7 and 12. It consists of a spring 17 riveted to the insideof the cone 4 by the rivets 18 and 19. To the outer or free end of thespring there is secured a pin 20 which has an enlarged portion near thespring and a neck or smaller portion 21 near the head of the pin, aswell as a head 22 on the pin. The stationary cone 3 is provided withthree holes, 23, 24 and 25 and slots 26 and 27 connecting said holes.

When it is desired to show a white light the pin 20 is pressed inwardlyuntil the neck 21 comes opposite the slots, when the bezel 5 and thecone 4 are revolved until the enlarged portion of the pin will comethrough the central hole 24, thus throwing Ithelenses 11 and 16 awayfrom the opening in'the cone 4. If it is desired to show the color ofthe lens 16, the pin 20 is pushed inwardly to the top 22 until the neckcomes opposite the slot and the cone 4 is revolved upwardly until theenlarged portion of the pin 20 is opposite the hole 23. Thismoveenlarged portion goes in the hole 23, thus locking'the cone againstmovement and positioning the lens-holder 12 in position. The oppositemovement will position the lens-holder 7 and the lens 11 opposite thecentral opening in the cone 1, thus projecting rays of the color of thelens 11 through the white lens 6.

It will be noted that in the construction herein shown, it is impossibleto position both lenses over the opening in the lantern at the sametime, for both operating pins are attached to the rotatable ring so thatwhen one lens-holder is positioned over the light-opening the otherholder is swung out by the pin acting in the straight part of theangular slot, and is locked by said pin sliding in the curved portion ofsaid angular slot, thus locking the other lens-holder in an inoperativeposition. Furthermore, when the ring is rotated so that the ring-lockingpin is in the hole-opening 24:, both lensholders are swung out intoinoperative po sitions and locked in said positions by the ring-lockingpin acting in conjunction with the two lens-holder operating pinssecured in said ring, which, as before stated, positively hold bothlens-holders swung in opposite directions out of operative position.

The form of the lens-holders may be changed somewhat and the method ofpositioning may be changed without departing from the spirit of myinvention, as my invention covers mechanism to change the colors of thelight rays projected from a lantern without the removal of the lenses orchanges other than adjustment in the mechanism controlling the lenses.

\Vhat I claim is 1. In a lantern, the combination of a body partprovided with an opening which shows the light therethrough, two holdershaving glass of different colors mounted therein, independent pivots forpivoting said holders to the body part of the lantern, a rotatable bezelmounted in the opening in the body part of the lantern, means connectingthe bezel and holders for positioning the glass of either one of saidholders in front of the opening in the body part of the lantern, andmeans for locking the bezel when one of the holders is in operativeposition and the other holder in inoperative position.

2. In a lantern, the combination of a body part having an openingtherein for the radiation of light, two adjustable holders secured tothe body of the lantern by independent pivots, glass of different colorsmounted in said holders, a rotatable bezel mounted in the opening of thebody part of the lantern having means connecting it to the holders forpositioning either of the holders in front of the opening to cause theradiation of light through the colored glass mounted therein, and alocking pin operable from the outside of the lantern body for positivelylocking the rotatable bezel in such position as to present one or theother of said holders in operative position.
